Loperamide HCL
Loperamide HCL is a synthetic opioid-receptor agonist used primarily as an antidiarrheal medication. It acts on the µ-opioid receptors in the intestinal wall to decrease gut motility, prolonging transit time and allowing increased absorption of fluids and electrolytes. Loperamide HCL is widely used in pharmaceutical formulations to treat acute and chronic diarrhea, including travelers’ diarrhea and diarrhea associated with inflammatory bowel disease. It is a white to off-white crystalline powder, highly soluble in water and commonly supplied in pharmaceutical grade for oral dosage forms.

Cetirizine Dihydrochloride
Cetirizine Dihydrochloride is a second-generation antihistamine widely used to relieve allergy symptoms such as hay fever, urticaria (hives), and other allergic conditions. It is the dihydrochloride salt form of cetirizine, presenting as a white to off-white crystalline powder that is odorless or nearly odorless and slightly bitter in taste. Cetirizine Dihydrochloride acts as a selective antagonist of peripheral H1 histamine receptors, preventing the effects of histamine and thereby reducing allergic symptoms without causing significant sedation. It is a commonly prescribed active pharmaceutical ingredient (API) in oral tablets, syrups, and capsules.
Cetirizine Hydrochloride
Cetirizine Hydrochloride is a widely used second-generation antihistamine effective for treating allergic conditions such as allergic rhinitis, chronic urticaria, and other allergy symptoms. It is the hydrochloride salt form of cetirizine, existing as a white to off-white crystalline powder with a slightly bitter taste. Cetirizine HCl acts by selectively blocking peripheral H1 histamine receptors, thereby reducing allergic symptoms without significant sedation or central nervous system depression. It is commonly formulated into tablets, syrups, and capsules as an active pharmaceutical ingredient.
Dicyclomine Hydrochloride
Dicyclomine Hydrochloride is an anticholinergic and antispasmodic agent used primarily to relieve smooth muscle spasms in the gastrointestinal tract.
